Summary

This study compares two types of dental onlays (custom-made tooth covers) for treating decayed teeth. 164 adults will each receive one milled and one 3D-printed onlay to see which lasts longer over 10 years. The goal is to find out if the newer 3D-printing method is as good as the standard milling technique.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Composite onlays (milled and 3D-printed) made with CAD/CAM technology
What this could lead to: If successful, this could show that 3D-printed onlays are as durable as milled ones, offering a more affordable and faster option for dental restorations.
What could go wrong: This is a long-term study (10 years) and results won't be available soon. The findings may not apply to all types of tooth decay or dental practices.
